FIELD OF THE DISCLOSURE

The present disclosure encompasses solid state forms of Rucaparib and of Rucaparib salts, and pharmaceutical compositions thereof.

BACKGROUND OF THE DISCLOSURE

Rucaparib chemical name is 8-fluoro-2-{4-[(methylamino)methyl]phenyl}-1,3,4,5-tetrahydro-6H-azepino[5,4,3-cd]indol-6-one, having the following chemical structure:

Rucaparib S-Camsylate chemical name is 8-fluoro-2-{4-[(methylamino)methyl]phenyl}-1,3,4,5-tetrahydro-6H-azepino[5,4,3-cd]indol-6-one ((1S,4R)-7,7 dimethyl-2-oxobicyclo[2.2.1]hept-1-yl) methane-sulfonic acid salt, having the following chemical structure:

Rucaparib Hemi-Edisylate chemical name is 8-fluoro-2-{4-[(methylamino)methyl]phenyl}-1,3,4,5-tetrahydro-6H-azepino[5,4,3-cd]indol-6-one Hemi-Edisylate, having the following chemical structure:

Rucaparib Tosylate chemical name is 8-fluoro-2-{4-[(methylamino)methyl]phenyl}-1,3,4,5-tetrahydro-6H-azepino[5,4,3-cd]indol-6-oneTosylate, having the following chemical structure:

Rucaparib is an inhibitor of the mammalian poly-adenosine 5′-diphospho-ribose polymerase (PARP) enzyme, indicated as monotherapy for the treatment of patients with deleterious BRCA mutation (germline and/or somatic) associated advanced ovarian cancer who have been treated with two or more chemotherapies. It was approved by the FDA as RUBRACA (Rucaparib Camsylate).

The compound is described in U.S. Pat. No. 6,495,541. A process for its preparation is described in U.S. Pat. No. 7,323,562, as well as in Org. Process Res. Dev., 2012, 16 (12), pp 1897-1904. US2004/0248879 had also described the following salts of Rucaparib: HCl, Mesylate, Phosphate, Glucuronate, Tartrate, Gluconate and Acetate. U.S. Pat. No. 7,268,126 described crystalline forms and an amorphous form of Rucaparib Phosphate. U.S. Pat. No. 8,754,072 described crystalline Camsylate and Maleate salts of Rucaparib. U.S. Pat. No. 9,045,487 described Camsylate and Maleate salts of Rucaparib.

Rucaparib is administrated in a high-load dose, of 600 mg twice daily; available tablets strength are 200 mg, 250 mg, and 300 mg.

WO 2016028689 describe tablet of Rucaparib camsylate in certain API amount. According to this application, at high drug loading, the contribution of the physical properties of the active pharmaceutical ingredient (“API”) to the manufacturability of a formulation is predominant. According to the applicant, high drug loading requires compressibility properties which are contributed due to the API. In that application, it is stated that Rucaparib camsylate has advantageous properties with respect to compressibility and that it is possible to manufacture tablets thereof with a load of 45% w/w or more

Polymorphism, the occurrence of different crystalline forms, is a property of some molecules and molecular complexes. A single molecule may give rise to a variety of polymorphs having distinct crystal structures and physical properties like melting point, thermal behaviors (e.g., measured by thermogravimetric analysis—“TGA”, or differential scanning calorimetry—“DSC”), X-ray diffraction (XRD) pattern, infrared absorption fingerprint, and solid state (¹³C) NMR spectrum. One or more of these techniques may be used to distinguish different polymorphic forms of a compound.

Different salts and solid state forms (including solvated forms) of an active pharmaceutical ingredient may possess different properties. Such variations in the properties of different salts and solid state forms and solvates may provide a basis for improving formulation, for example, by facilitating better processing or handling characteristics, changing the dissolution profile in a favorable direction, or improving stability (polymorph as well as chemical stability) and shelf-life. These variations in the properties of different salts and solid state forms may also offer improvements to the final dosage form, for instance, if they serve to improve bioavailability. Different salts and solid state forms and solvates of an active pharmaceutical ingredient may also give rise to a variety of polymorphs or crystalline forms, which may in turn provide additional opportunities to assess variations in the properties and characteristics of a solid active pharmaceutical ingredient.

Discovering new solid state forms and solvates of a pharmaceutical product may yield materials having desirable processing properties, such as ease of handling, ease of processing, storage stability, and ease of purification or as desirable intermediate crystal forms that facilitate conversion to other polymorphic forms. New solid state forms of a pharmaceutically useful compound can also provide an opportunity to improve the performance characteristics of a pharmaceutical product. It enlarges the repertoire of materials that a formulation scientist has available for formulation optimization, for example by providing a product with different properties, e.g., a different crystal habit, higher crystallinity, or polymorphic stability, which may offer better processing or handling characteristics, improved dissolution profile, or improved shelf-life (chemical/physical stability). For at least these reasons, there is a need for additional solid state forms (including solvated forms) of Rucaparib.

DETAILED DESCRIPTION OF THE DISCLOSURE

The present disclosure encompasses solid state forms of Rucaparib and of Rucaparib salts. Solid state properties of solid state forms of Rucaparib and salts thereof can be influenced by controlling the conditions under which the solid state forms of Rucaparib and of Rucaparib salts are obtained.

A solid state form (or polymorph) may be referred to herein as polymorphically pure or as substantially free of any other solid state (or polymorphic) forms. As used herein in this context, the expression “substantially free of any other forms” will be understood to mean that the solid state form contains about 20% (w/w) or less, about 10% (w/w) or less, about 5% (w/w) or less, about 2% (w/w) or less, about 1% (w/w) or less, or about 0% of any other forms of the subject compound as measured, for example, by XRPD. Thus, solid states forms of Rucaparib and salts thereof described herein as substantially free of any other solid state forms would be understood to contain greater than about 80% (w/w), greater than about 90% (w/w), greater than about 95% (w/w), greater than about 98% (w/w), greater than about 99% (w/w), or about 100% of the subject solid state form of Rucaparib or salt thereof. In some embodiments of the disclosure, the described solid state forms of Rucaparib or salts thereof may contain from about 1% to about 20% (w/w), from about 5% to about 20% (w/w), or from about 5% to about 10% (w/w) of one or more other solid state forms of the same Rucaparib or salt thereof.

As used herein the term “crystalline Form X1” in relation to crystalline Rucaparib base refers to crystalline Rucaparib base characterized by an XRPD pattern having peaks at 8.0, 13.1, 14.7, 16.6, 17.5, 23.8 and 28.6 degrees 2-theta±0.2 degrees 2-theta. As used herein the term “crystalline Form X₂” in relation to crystalline Rucaparib base refers to crystalline Rucaparib base characterized by an XRPD pattern having peaks at 7.2, 12.4, 13.9, 15.6, 16.0, 23.6, 24.9, 25.5, 26.4 and 32.6 degrees 2-theta±0.2 degrees 2-theta.

Depending on which other solid state forms a comparison is made, the crystalline forms of Rucaparib and salts thereof of the present disclosure have advantageous properties selected from at least one of the following: chemical purity, flowability, solubility, dissolution rate, morphology or crystal habit, stability—such as chemical stability as well as thermal and mechanical stability with respect to polymorphic conversion, stability towards dehydration and/or storage stability, low content of residual solvent, a lower degree of hygroscopicity, flowability, and advantageous processing and handling characteristics such as compressibility, and bulk density.

A solid state form, such as a crystal form or an amorphous form, may be referred to herein as being characterized by graphical data “as depicted in” or “as substantially depicted in” a Figure. Such data include, for example, powder X-ray diffractograms and solid state NMR spectra. As is well-known in the art, the graphical data potentially provides additional technical information to further define the respective solid state form (a so-called “fingerprint”) which cannot necessarily be described by reference to numerical values or peak positions alone. In any event, the skilled person will understand that such graphical representations of data may be subject to small variations, e.g., in peak relative intensities and peak positions due to certain factors such as, but not limited to, variations in instrument response and variations in sample concentration and purity, which are well known to the skilled person. Nonetheless, the skilled person would readily be capable of comparing the graphical data in the Figures herein with graphical data generated for an unknown crystal form and confirm whether the two sets of graphical data are characterizing the same crystal form or two different crystal forms. A crystal form of Rucaparib or salt thereof referred to herein as being characterized by graphical data “as depicted in” or “as substantially depicted in” a Figure will thus be understood to include any crystal forms of Rucaparib or salt thereof characterized with the graphical data having such small variations, as are well known to the skilled person, in comparison with the Figure.

As used herein, and unless stated otherwise, the term “anhydrous” in relation to crystalline forms of Rucaparib and salts thereof, relates to a crystalline form of Rucaparib or salt thereof which does not include any crystalline water (or other solvents) in a defined, stoichiometric amount within the crystal. Moreover, an “anhydrous” form would typically not contain more than 1% (w/w), of either water or organic solvents as measured for example by TGA.

The term “solvate,” as used herein and unless indicated otherwise, refers to a crystal form that incorporates a solvent in the crystal structure. When the solvent is water, the solvate is often referred to as a “hydrate.” The solvent in a solvate may be present in either a stoichiometric or in a non-stoichiometric amount.

As used herein, the term “isolated” in reference to solid state forms of Rucaparib and salts thereof of the present disclosure corresponds to a solid state form of Rucaparib or salt thereof that is physically separated from the reaction mixture in which it is formed. The step of isolating solid state forms of Rucaparib or solid state forms of salts of Rucaparib may be performed by crystallization or precipitation.

As used herein, unless stated otherwise, the XRPD measurements are taken using copper Kα radiation wavelength 1.54184 Å. XRPD peaks reported herein are measured using CuK α radiation, λ=1.5418 Å, at a temperature of 25±3° C.

A thing, e.g., a reaction mixture, may be characterized herein as being at, or allowed to come to “room temperature” or “ambient temperature”, often abbreviated as “RT.” This means that the temperature of the thing is close to, or the same as, that of the space, e.g., the room or fume hood, in which the thing is located. Typically, room temperature is from about 20° C. to about 30° C., or about 22° C. to about 27° C., or about 25° C.

The amount of solvent employed in a chemical process, e.g., a reaction or crystallization, may be referred to herein as a number of “volumes” or “vol” or “V.” For example, a material may be referred to as being suspended in 10 volumes (or 10 vol or 10V) of a solvent. In this context, this expression would be understood to mean milliliters of the solvent per gram of the material being suspended, such that suspending a 5 grams of a material in 10 volumes of a solvent means that the solvent is used in an amount of 10 milliliters of the solvent per gram of the material that is being suspended or, in this example, 50 mL of the solvent. In another context, the term “v/v” may be used to indicate the number of volumes of a solvent that are added to a liquid mixture based on the volume of that mixture. For example, adding solvent X (1.5 v/v) to a 100 ml reaction mixture would indicate that 150 mL of solvent X was added.

A process or step may be referred to herein as being carried out “overnight.” This refers to a time interval, e.g., for the process or step, that spans the time during the night, when that process or step may not be actively observed. This time interval is from about 8 to about 20 hours, or about 10-18 hours, typically about 16 hours.

As used herein, the term “reduced pressure” refers to a pressure that is less than atmospheric pressure. For example, reduced pressure is about 10 mbar to about 50 mbar.

As used herein and unless indicated otherwise, the term “ambient conditions” refer to atmospheric pressure and a temperature of 22-24° C.
